All I can say is Wow. I'm a nurse, and dealing with a father with pancreas CA.
I had no idea that a Whipple is done for pancreatitis and/or benign findings. Testing and a needle biopsy would have shown whether the tumor was cancerous. A person should not have to go to the extent of a Whipple for diagnosis. Since the head of the pancreas was removed, are you now symptomatic of diabetes?
